Very often a copyright agreement does not permit the author to upload his/her papers to public web-sites, but permits to send it to other researchers upon individual requests. So, if you need a paper you can ask the author to send you the corresponding file or reprint.
Here, in Researchgate., You can access those publications that you have uploaded on the platform. Once you have accessed them you will have at your disposal a "citations" tag, then you will have information of those who have cited it and who make life within this community. In the case that they have uploaded the content of the publication that refers to your publications you can access them, otherwise, ask them via private message.
